I've had my A129 Duo since about May 2020 only. Took it down today to get stuff of the SD card and noticed this. Seems to be a sub-assembly for Viofo to easily customise the port cutouts. However, it's cracking and bulging somewhat (pushing another side in). I'm concerned that crack would go all the way and then I'll have one chunk of plastic coming off my A129 body (yay for better cooling!). Anyone else experiencing this? Or is it uniquely tropical (yes I use parking mode with 6 hour timer, doing 2 fps time lapse). This car is seldom driven, most of the time parked under shade. Clocks maybe 30-50 km/week the last 1.5 years.

That socket does get quite warm, so it may be heat related, but it is high temperature plastic so should be OK. I don’t think it is going to fall apart.
 
Did the socket place suffer a hit? Do you use the supplied USB cable?

Camera was installed since day 1 using HK3-ACC only. Never plugged into anything else.
